To an whom it may comer-n:

- qBe it known that I, MARLEY F OTHERING- HAM HAY, a citizen of GreatBritain, resident at Fiumc, Austria-Hungary, hate invented certain newand useful Improvements inand Relating to Devices for Regulating thesubmersion of Submarine Boats and the Like, of which the following is aspecification.

The object of this invention a device" for regulating the submersion ofsubmarine boats and the like by means of a pump con nected to a tank.v

- It has moreparticularly in view to allow the application of a rotarypump turning in one direction only, with the object of subjecting thecontrol of the device to a single distributing cock, thus simplifyingthe .Working, and obviating errors.

' tank a (Fig. l) is placed in such a way that its center of gravitylies in the'vrertical line passing through the center of volume of theconning tower b; This tank is connected by g .j a..p ipe 0 to the casingcl of a reverser having two outlets, one 6' leading to the sea, and

the-other f being connected to the delivery .offthe pump g ofany'suitable construction.

"These plpes are distributed about the peri'phery of the casingsymmetrically. The

suction pipe h of the said pump terminates in an annular chamber 11(Fig. 4)., at the lower part of the casing cl, and communicating -withthe interior of said casing by means of openings 9, t, u, of varyingsuit-able size, distributed over its periphery. \Vithin this'casing (Zis a plug j, divided by means ofa vertical partition 7.: into twoindependent'compartments m, n. The compartmentm has two openings 0, 7),superposed, and arranged to be capable ofcommunicating with the pipes 0,c f, and the annular chamber a, In the compartment a, inthemplane of the"upper p1p1ng, is an opening 9' having a Specification of LettersPatent.

width equal to that of the compartment, and

in the plane of the annular chamber 2', is an opening 7-, beneath the'central'portion of and coaxial with the opening g, and corre spondingin dimension to an opening a through the wall of the casing andcommunicating with annular chamber 2'.

The working is as follows: When it is desired to fill the ballast tankfor diving, the pump is set going, and the controlling member is broughtinto the position of Figs, 3 and at. The piping 6, leading to the sea,is

by means of the opening 0, put into column-.-

nication with the compartment m, itself connected by oppositeopenings 1) and u with the annular chamber 2', and consequently with thesuction h of the pump. Thedeliv ery f of this pump is directlyconnected, by

-' means of the opening g of'the compartment a, with the pipe 0 leadingto the tank...

.VVhen the ballast tank is sufli cient-ly filled and the submarinebegins to dive, the cock ot the controlling member is turned in thedirection indicated by the arrow, so as to bring it into the position ofFig. 5. Durin this rotation the suction opening connecte with the sea,is progressively closed, as also is the delivery pipe leading to thetank by means of the edge of opening 9. As soon as the plug begins toturn, the opening 21 (Fig. 4) comes into position opposite the opening aand the water arriving from the delivery of the pump through'the pipefis divided into two parts, one of which flows to the ballast tank,while'the other returns through the annular chamberz' and the pipe '71.to the suction of the pump. When the controlling member arrives in theposition of Fig. 5, the opposite openings t and r (Fig. 4), place thesuction 'h of the pump in communication with the compartment m, which isconnected by the opening q with' delivery 1. The pump is thus'short-circuited, its delivery corresponding with its suction, andit cancontinue to work at the same speed without any increase of resistance inthe delivery and consequent increase of load being pro- '6 is embeds 1zres of Fig-, 6, as ,sltption of 'thg. commun cates OPBQT;

site openings p and s, with the compartment m of the regulator, which isconnected by the opening 0 to the pipe 0 communicating with the tank.Again, the delivery t of the pump is directly connected by the opening 9.of the compartment 11., with the pipe 6 leading to the sea, so thatthepump sucks from the ballasttankand expels into the sea, causing theboat to rise.

The advantages'are as follower The in vention allows the quantity ofwater contained in the ballast tanks of a submarine boat to be variedwithout afiecting the speed ot'the pump which can thus work constantlyat full speed. By this means maneuvering errors are avoided, as well asdamage resultpump, in combination with a distributingcock -1nterp0se dan said condults and having passages so arranged that in'one position it'ing from failure by the pump to pick up the suction when stopped andset going again at .each change 1n direction 0t suctlon. The

arrangement of the regulator makes it pos sible, by means of anincomplete opening of orifices 0, p, g, r, to vary with precisionthequantity of water sucked up by the pump without varying its speed andwithout increasing-the pressure of its delivery. The

'degi'ee of immersion of a submarine may -municating with the ballasttank, the external water,- and the inlet and outlet of the connects'thesuction side of the pump to the external water and the discharge side ofthe pump to the tank, whereby the tank may be filled; in anotherposition it connects the suction side of the pump'to thetank andthedischarge side to the external wate r, whereby thetank may be emptied;and in a third position it'connects the suction side of I' the pumptothe discharge sidethereofl' whereby the pump may be driven constantly inthe same direction, and by manipulating the annular'chamber 2'.
